First period after miscarriage

I went through a miscarriage during thanksgiving and still waiting for my AF..... I was only 6 weeks. Dr. Said it was a chemical. But I still haven’t gotten my period. On 12/22 I had VERY little brown spotting. Only when I wiped. It wasn’t constant. It was brown/light pink. It lasted until 12/27 so for five days. Anyways was this my AF? It wasn’t heavy at all. And it did not require the use of a pad or tampons. Which I heard a period should be the use of a pad/tampon and a regular flow. Anyways I’ve taken pregnancy test and all negative. Could this be a new pregnancy and to early to test? How was your first AF after a miscarriage? Light? Heavy?!
